    \brief The geoSatelliteInfo type represents basic information about a
    satellite.
 
    This type is a QML representation of \l QGeoSatelliteInfo. The type is
    uncreatable from QML and can only be used when handling satellite updates
    from \l SatelliteSource.
 
    This type contains the \c satelliteSystem, \c satelliteIdentifier and
    \c signalStrength read-only properties, and also optional attributes.
 
    Use the \l hasAttribute method to check if the attribute exists or not,
    and the \l attribute method to get its value.
 
    \sa QGeoSatelliteInfo

    \qmlproperty enumeration QtPositioning::geoSatelliteInfo::satelliteSystem

    \value GeoSatelliteInfo.Multiple This type normally indicates that the
           information is received from a device that supports multiple
           satellite systems, and the satellite system is not explicitly
           specified.
    \value GeoSatelliteInfo.CustomType The first type that can be used
           for user purposes.

    Returns the value of the attribute \a attr or -1 if the value has not been
    set.
 
    The following attributes are supported:
 
    \list
        \li \c {GeoSatelliteInfo.Elevation} - the elevation of the satellite,
            in degrees.
        \li \c {GeoSatelliteInfo.Azimuth} - the azimuth to true north,
            in degrees.

/*!
    \qmlmethod bool QtPositioning::geoSatelliteInfo::hasAttribute(Attribute attr)
 
    Returns \c true if the satellite information contains the attribute \a attr.
    Otherwise returns \c false.
 
    See \l attribute() for the list of supported attributes.
